WRECKING-MACHINE OR STUMP-EXTRACTQR.

SPECIFICATION forming part of Letters Patent No. 468,644, dated February9, 1892. Application filed August 14, 1891. Serial No. 402,671. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN CoRNELrUs,of Oakland, in the county of Garrettand State of Maryland, have invented a new and useful Improvement in a\Vrecking-Machine or Stump- Extractor, of which the following is aspecification.

My invention is an improved wrecking-machine or stunippuller, and hasfor an object, among others, to provide a simple construction ofcombined machine which will possess thenecessary strength, be easilyconvertible to either an elevated wrecking-machine or a flatpulling-machine, and may be conveniently arranged for extraordinarypower or for a medium power and a somewhat faster speed or for a lessdegree of power and a high rate of speed, so that the machine can beadvantageously used for light work where a fast movement is desired, forsomewhat heavier work with a slower speed, or for the heaviest work, asoccasion may require.

The invention consists in certain features of construction and novelcombinations of parts, as will be hereinafter described, and pointed outin the claims.

In the drawings, Figure 1 is a side view, Fig. 2 an end view, and Fig. 3a top plan view, of the machine arranged for wrecking and geared up forthe heaviest work. Fig. A is a top plan view of the machine geared forlight work. Fig. 5 shows the sweep in detail. Fig. 6 is a detail View ofa part of the bedplate, and Fig. 7 is a detail view illustrating theapplication of the runners directly to the base-frame.

In carrying out my invention I employ a framing including a base or bedA, having at its four corners socket-like parts 13 for the upper ends ofthe uprights or legs 0, which uprights are pivoted by bolts D in saidsockets, so that they can be adjusted to spread the machine in order toraise or lower the bed-plate A to the desired height. The end uprightsare joined together by means of connectingbars E, having a plurality ofbolt-holes e at one end, so that their connection with one of theuprights may be set to permit the adjustment of the legs by spreading ordrawing together, as before indicated. Thus it will be seen thebed-plate may be set to and held at any height within the limits of themachine, or may be lowered to rest flat on the ground or the skids,presently referred to, when a low machine is desired. It will also beunderstood that, where 5 5 desired, the bed-frame maybe bolted orotherwise secured on a truck or similar carriage to facilitate theloading of safes and similar weighty objects thereon. At their lowerends the legs or uprights O fit in sockets F on the skids or runners Gand are secured therein by pinsf. It is manifest that by hitching ahorse or team to the said runners the machine can be easily moved fromplace to place.

Where desired-as, for instance, when the pulling or lifting is extraheavy-the bedplate may be braced and further supported by intermediateuprights orlegs H, fitted at their upper ends in sockets h on thebed-plate and at their lower ends in sockets h on the skids.

In adjusting the machine for use as a low or flat puller theseintermediate sockets 71. may be removed from the runners and the bed hefitted down on the said runners between the sockets F and bolted to therunners, as shown in Fig. 7, to which end I provide the bed-plate withlugs I I, perforated for the fastening-bolts, as shown.

In practice the bed-plate is preferably cast of steel or other suitablemetal, with the several socket-pieces and lugs integral, and I form thesaid bed with the top plate at, having the opening a, through which thecable and chain can hang, and with the edge flange-like portion A, whichis preferably beveled outward on itsinner surface and extends entirelyaround the edge of the top plate.

The pulling mechanism upon the top plate includes the main wheel J,which is composed of the worm-wheel made in the two side sections K K,the chain-wheel L, between the said sections, and the drums M, arrangedoutside the worm-Wheel sections and receiving the cables on, which maybe connected at their lower ends with suitable grabs X for engaging thework to be lifted. The chain N, working in chain-wheel L, may also hangdown and connect with the grabs, so that the chain and cable may be usedjointly or either the chain or cables may be used alone; also, in theuse of the machine on the ground the cables may lead off and connectwith the work and the chain may lead from the work in through theinlet-guide N, around the chain-wheel, and out through the stripperguide0, and in such use of the machine either the cables or chain, or both,can be used; but for heavy work I prefer, in all instances, to use boththe cables'and the chains.

The main wheel is journaled in bearings in the side frames P, which arecast on the bed and have removable caps p. To turn the main wheel Iprovide the worm Q, formed to mesh with the worm-Wheel sections andjournaled in a frame R, which has upperand lower plates 0" and aconnecting-plate r, the latter having lugs for the bolt or rod S, bywhich the frame It is pivoted at one end. By thus pivoting the frame Rat one end it may be adjusted to throw the worm into or out of mesh withthe worm-wheel sections and the said parts may be secured in mesh by thelocking-rod T. The upper and lower plates 0" are provided at r withbearings for the gearshaft U, which shaft, like the shaft of the worm,is extended upward and the upper ends of both shafts are adapted toreceive the-large and small gear-wheels V and '0, and such wheels V andi) may be used in any desired relation, the small wheel 12 being placedon the worm-shaft and the large wheel V on the gear-shaftU for smallpower and high speed, or Vice versa, for medium power and a slowerspeed. For extra heavy work, however, I

prefer to use a Worm-wheel WV on the upper end of'the shaftof worm Q andto provide a drive-worm X for meshing said worm-wheel.

The shaft of worm X journals in bearings in the frame Yand extends atboth ends beyond the said bearings, being adapted at said ends toreceive the hand-cranks Z and the chainwheel'l, the chain 2 being passedover the said wheel 1 and down in convenient reach from the ground. Bythis chain the operator can from the ground turn the horizontaldriveworm and through the connections described turn the main wheelwithout going up on the machine. This will be found useful in lightwork; but for heavy work I intend to place a man at the cranks on bothends of the driveshaft, step-boards 3 being supported on arms 4 on thelegs 0, such boards 3 being arranged to form a secure footing for themen at the cranks. By means of this drive-worm and the otherconstruction described I am able to get power sufficient for theheaviest work.

'llhedrive-worm is keyed on its shaft by a cross pin or pins 6, and onthe shaft between the said worm and the hearings in the frame Y, I placewashers 7 loose on the shaft, so that by removing the pin 6 the shaftand its worm may be removed.

It will be seen from the foregoing description that the several changesto adapt the machine for extra heavy work, for medium work withaslowspeed, and for lightwork with afast speed may be easily and quicklymade. It will also be seen that by the arrangement of the upright ormain worm and the gear-shaft in the movable or pivoted frame the mainworm may be quickly set into and out of gear with the worm-wheelsections. To move the said frame from the ground,I provide alever 8,pivoted at 9, so that it can rock on said pivot and also be swungslightly in a direction at a right angles to said rocking motion.Thelower end of this lever extends in convenient reach from the ground,while its upper end connects by a link 10 with the swinging end of theframe R, so that the lever can be operated to throw such frame in orout. When the frame R is thrown in, thelever is engaged and locked by ahook 11, which serves also to lock the poses where a strong pull or liftis required, 7

and it will be readily seen that, While the machine is capable of theheaviest work, it may be quickly adjusted by means of theinterchangeable parts to permit it to be used with advantage on thelightest work where speed is desired.

My machine is especially desirable in wrecking, and in such use, when itis desired to remove a wrecked car or cars from the track, the machinemay be anchored and'its cable be passed through a block connected withsuch car and then run off to one side and be provided at its end with ananchor-hook similar to the half of an ordinary marine, anchor, such hookbeing driven into the ground, when the machine may be operated toquickly pull the car to any desired position.

In order that the machine may be operated by a horse in both itselevated and lowered positions, I provide a sweep-support 13 of aspecial construction, having at one end a socket to fit on the shaft ofeither the main worm-wheel or of the gear-shaft and having its portion14 next the said socket formed to provide a horizontal seat for thesweep-bar 15 when the machine is down on the ground, and having at theend opposite such socket a downwardly-inclined portion 16 to form a seatfor the sweep-bar 15 when the machine is elevated on its legs, suchinclination of the seat 16 serving to throw the outer end of the sweepdown sufficiently low for a horse to be hitched thereto, the change ofthe sweep from a high to a low machine requiring only the removal andreplacing of a few bolts.
